rt2x00: Convert rt2800pci to use tasklets
Fix interrupt processing on slow machines by using individual tasklets
for each different device interrupt. This ensures that while a RX or TX
status tasklet is scheduled only the according device interrupt is
masked and other interrupts such as TBTT can still be processed.
Also, this allows us to use tasklet_hi_schedule for TBTT and PRETBTT
processing which is required to not send out beacons with a wrong DTIM
count (due to delayed periodic beacon updates). Furthermore, this
improves the latency between the TBTT and sending out buffered multi-
and broadcast traffic.
As a nice bonus, the interrupt handling overhead is reduced such that
rt2800pci gains around 25% more throuhput on a rt3052 MIPS board.
